The negative environmental impacts of chemical fertilizers have been recognized for a long time, and the returning agricultural residues to soil is considered sustainable practice. However, few studies focused on ecological economic benefits simultaneously. Using 16-year field experiment, we integrally evaluated compared six fertilization practices. treatments included no-fertilizer control, conventional NPK fertilization, partial substitutions in with low (30%) or high (60%) level (straw cattle manure). amount N, P K inputs remained constant across all treatments, but source differed. Ecological were assessed through study ecosystem multifunctionality co-occurrence network analysis micro-food web. Our results showed that applications increased microbial biomass diversity, complexity, alone. high-level straw substitution treatment supported greatest complexity. Random Forest regression revealed fungal diversity important biological traits associated multifunctionality. benefit was highest when manure returned soil, lowest crop intermediate Therefore, return provided comprehensive services. findings increase understanding relationships between effects soil.

Seed biopriming for sustainable agriculture and ecosystem restoration

Microbial Biotechnology, Journal Year: 2023, Volume and Issue: 16(12), P. 2212 - 2222

Published: July 25, 2023

Abstract The utilization of microbial inoculants in the realm sustainable agricultural and ecosystem restoration has witnessed a surge recent decades. This rise is largely attributed to advancements our understanding plant–microbe interactions, urgency reduce dependence on agrochemicals growing societal demand for strategies management. However, despite rapid growth bio‐inoculants sector, certain limitations persist concerning their efficacy performance under field condition. Here, we propose that seed biopriming, an effective inoculant technique integrating both biological agents (the priming beneficial microbes seeds) physiological aspects (hydration seeds improved metabolically activity), significant potential mitigate these limitations. method increases protection against soil‐borne pathogens soil pollutants, such as salts heavy metals, while promoting germination rate uniformity, leading overall primary productivity health. Furthermore, argue coating can facilitate transgenerational associations microbes, refine plant microbiomes, maintain legacies microflora. review article aims improve biopriming approach potent valuable tool achieving agriculture successful restoration.

Effects of continuous cropping on bacterial community diversity and soil metabolites in soybean roots

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 10, 2025

The alternating planting of corn and soybeans is regarded as an effective strategy in addressing the challenges faced soybean cultivation. However, precise mechanisms that control bacterial microbiome roots soil, particularly continuous cropping rotational corn–soybean farming rotations, are remain unclear. This study employed both field pot positioning experiments, using high-throughput generic metabolomics sequencing techniques to explore dynamics between plants, root microflora, soil metabolites, especially context fluctuating crop rotation. process included rotating significantly enhanced their grain yield, dry weight, nitrogen concentration, urease activity, well accumulation nitrogen, phosphorus, potassium various plant organs, compared traditional practice There a significant reduction transit operational taxonomic units (OTUs) from rhizosphere endosphere through rhizoplane. number OTUs consumed enriched on rhizoplane greater than those absorbed endosphere. Continuous practices boost Burkholderiales, whereas chloroplast microorganisms improve rotation techniques. Soil environmental factors, such accessible crucial establishing relative prevalence Rhodanobacter other groups. benzyl alcohol, show positive correlation with Cyanobacteria, while acidic compounds, D-arabinitol, positively linked Burkholderiales. indicates crops facilitates growth soybeans, increases nutrient plants enhances presence beneficial bacteria, improves yields.

From salty to thriving: plant growth promoting bacteria as nature’s allies in overcoming salinity stress in plants

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: June 23, 2023

Soil salinity is one of the main problems that affects global crop yield. Researchers have attempted to alleviate effects salt stress on plant growth using a variety approaches, including genetic modification salt-tolerant plants, screening higher genotypes, and inoculation beneficial microbiome, such as growth-promoting bacteria (PGPB). PGPB mainly exists in rhizosphere soil, tissues surfaces leaves or stems, can promote increase tolerance abiotic stress. Many halophytes recruit salt-resistant microorganisms, therefore endophytic isolated from help enhance responses. Beneficial plant-microbe interactions are widespread nature, microbial communities provide an opportunity understand these interactions. In this study, we brief overview current state microbiomes give particular emphasis its influence factors discuss various mechanisms used by alleviating for plants. Then, also describe relationship between bacterial Type VI secretion system promotion.

Abstract Alkaline lakes are extreme environments inhabited by diverse microbial extremophiles. However, large-scale distribution patterns, environmental adaptations, community assembly, and evolutionary dynamics of communities remain largely underexplored. This study investigated the characteristics on rare abundant taxa in alkaline lake sediments west northwest China. We observed that varied significantly with geographical distance, while remained unaffected regional differences. The assembly process was influenced dispersal limitation, whilst were predominantly driven heterogeneous selection. Network analysis indicated as core species for interactions stability. Rare exhibited higher speciation transition rate than taxa, serving a genetic reservoir potential candidates to become abundance highlighting their crucial role maintaining diversity. These insights underscore significant influence ecosystem biodiversity stability lakes.
